1,4-Dihydroindeno[1,2-c]pyrazoles with Acetylenic Side Chains as Novel and Potent Multitargeted Receptor Tyrosine Kinase Inhibitors with Low Affinity for the hERG Ion Channel
摘要:
The synthesis of a novel series of 1,4-dihydroindeno[1,2-c]pyrazoles with acetylene-type side chains is described. Optimization of those compounds as KDR kinase inhibitors identified 8, which displayed an oral activity in an estradiol-induced murine uterine edema model (ED50 = 3 mg/kg) superior to Sutent (ED50 = 9 mg/kg) and showed potent antitumor efficacy in an MX-1 human breast carcinoma xenograft tumor growth model (tumor growth inhibition = 90% at 25 mg/kg.day po). The compound was docked into a homology model of the homo-tetrameric pore domain of the hERG potassium channel to identify strategies to improve its cardiac safety profile. Systematic interruption of key binding interactions between 8 and Phe656, Tyr652, and Ser624 yielded 90, which only showed an IC50 of 11.6 mu M in the hERG patch clamp assay. The selectivity profile for 8 and 90 revealed that both compounds are multitargeted receptor tyrosine kinase inhibitors with low nanomolar potencies against the members of the VEGFR and PDGFR kinase subfamilies.
The present invention relates generally to bis-amide group containing pharmaceutical agents, and in particular, to multicyclic bis-amide MMP-13 inhibitor compounds. More particularly, the present invention provides a new class of MMP-13 inhibiting compounds, containing a pyrimidinyl bis-amide group in combination with a heterocyclic moiety, that exhibit an increased potency and solubility in relation to currently known bis-amide group containing MMP-13 inhibitors.

The disclosure provides compositions and methods for sensitizing primary HIV-1, including transmitted/founder viruses, to neutralization by monoclonal antibodies, e.g., those directed against CD4-induced (CD4i) epitopes and the V3 region. In certain embodiments, the disclosure relates to the use of small molecules as microbicides to inhibit HIV-1 infection directly and to sensitize primary HIV-1 to neutralization by readily elicited antibodies.

based on computational, thermodynamic, and crystallographic data, of a series of small-molecule ligands of the Phe43 cavity of the envelope glycoprotein gp120 of human immunodeficiency virus (HIV) has been achieved. Importantly, biological evaluation revealed that the small-moleculeCD4mimics (4–7) inhibit HIV-1 entry into target cells with both significantly higher potency and neutralization breadth
